Micronutrients, particularly Zinc (Zn), play a vital role in the growth and development of plants due to its catalytic effect on many metabolic processes. However, the varietal responses to growth and yield vary significantly. A screening experiment was conducted to know the growth and yield response of six capsicum hybrids viz., Indra, Priyanka, Inspiration, Massilia, Bachata and Local green with two levels of ZnSO4 (with and without  ZnSO4) as basal soil application. The growth and yield attributes at harvest stage was recorded. The dry matter production (DMP) and fresh fruit yield was also noted for all the six hybrids. Results revealed that, Zn fertilisation significantly improved the plant height, root growth, fruit development as well as fresh fruits yield. Higher plant height (83 cm), root length (37 cm), root volume (13 cc), fruit numbers, fruit weight (15 and 133g), fruit length, girth, pericarp thickness (9.17, 8.25 and 0.67 cm), DMP (65.0 g pot-1) as well as fresh fruit yield (4.70 kg pot-1) were observed with Indra followed by Inspiration and Bachata. Lesser response for the Zn application was noticed with the local green hybrid for various growth and yield traits. Indra was found to be highly responsive to Zn fertilisation while Inspiration, Bachata, Massilia, and Priyanka were medium responsive and local green hybrid was observed to be less responsive to Zn fertilisation.

Aim: Nutri cereals are the earliest foods known to humans, but urbanisation and industrialisation have diminished their cultivation and consumption due to large-scale rice and wheat cultivation. Hencee, the present study aims to know the buying behavior of Nutri cereals among the people inthe Coimbatore District.

Study Design: Totally 100 consumers were selected by proportionate random sampling. Primary data was collected from the respondents by using well-structured interviews scheduled between October 2021 and November 2021

Methodology: Percentage age analysis and Garrett’s ranking techniques were used to analyze the data.

Results: Results revealed that nutrient content and better quality are the major factor influencing the purchase of Nutri cereals. Therefore, the development of customized products in Nutri cereal products category and proper promotion measures should help the policymakers to increase consumption among the people.

Coconut (Cocous nucifera), also known as the "tree of heaven," is one of the most important marketable crops in tropical countries. Research and commercialization of the technology is needed as to provide an additional source of income and to improve the economic status of the farmers and the country. Some physical and engineering features such as size, weight, sphericity, roundness, volume, and density were researched as part of the steps toward developing processing and handling equipment for coconuts. Major diameter varied from 132.23 mm to 101.45 mm with a mean value of 117.24 mm, the seed volume varied from 713.45 cm3 to 425.88 cm3, with an average density of 1.0427 g cm-3. The roundness ranges from 0.4607 to 0.8216 with a mean value of 0.6490 and the sphericity ranges from 0.7304 to 0.9561 with a mean value of 0.8330.

Microbial fuel cell (MFC) is a favourable platform for continuous energy generation and monitoring wastewater treatment due to the electrochemically active microbes backing. Their considerable usage is in removing pollutants or toxic elements as a water softener in biosensors and formation of a few compounds. Despite various drawbacks predominantly including insufficient power supply, frequent noticeable growth in microbiological, chemical, and electrochemical viewpoints enables envisioning microbial fuel cell (MFC) biosensors as standard future analytical technology. This review summarizes the basic concepts, general understanding of the important associated terms with examples. The in situ online monitoring approach draws a special attention to the applicability part that majorly entails quantitative analysis of BOD and toxicants, along with additional benefits like monitoring specific microbial activity, MIC sensing, powering other sensors externally, antibiotic detection etc. Insight to modern strategies including miniaturization along with modified versions for better sensing is also provided. This paper briefs the microbial fuel cell (MFC)s as biosensors including the challenges and its future perspective.

The most frequently used building material on this planet is concrete. Concrete is the supreme user of natural resources as a result of its widespread use as construction material. Cement production produces significant amount of greenhouse emissions. The protection of environment has become challenging in many developing countries, 7-8% of CO2 is produced by the cement industry that causes huge damage to the environment. In concrete production, and limestone can be a partial alternative to cement. The limestone waste is transported and disposed in landfills. The disposal of limestone waste material in the open areas is causing several problems. In this study, the properties of concrete incorporating limestone waste are reviewed. Workability, compressive strength, split tensile strength, flexural strength, modulus of elasticity, and durability are among qualities of limestone waste concrete that have been discussed in this study. The cement was replaced by limestone waste in the ratio of 25% to 30% in concrete By limiting the waste of limestone in the concrete, cement content can be reduced, which turns into an eco-friendly solution.
